           Summary: kdevelop crashes while parsing cmake list containing
                    execute_process with unset variable
           Product: kde
           Version: unspecified
          Platform: Unlisted Binaries
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: crash
          Priority: NOR
         Component: general
        AssignedTo: unassigned-bugs at kde.org
        ReportedBy: krnekit at gmail.com


Application that crashed: kdevelop.bin
Version of the application: 4.0.0 (using KDevPlatform 1.0.0)
KDE Version: 4.3.5 (KDE 4.3.5)
Qt Version: 4.5.3
Operating System: Linux 2.6.31.13-desktop-1mnb x86_64
Distribution: "Mandriva Linux 2010.0"

What I was doing when the application crashed:
I'm using KDevelop 4.0.0 on Mandriva 2010.0 with KDE 4.3.5. The following
fragment of the CMakeLists.txt cause the program to crash:

#set(cmd ls)
execute_process(COMMAND "${cmd}")

Though, the following code works fine:

set(cmd ls)
unset(cmd)
execute_process(COMMAND "${cmd}")
